LIFT AND CARRIER TRAILER APPARATUS BACKGROUND OF THE INVENTION Trailerapparatus having a turntable on a trailer and an implement lift andsupport assembly mounted on the turntable.

Many farm implements such as three-point hitch planters, cultivators andetc., are very wide, for example feet wide in a direction transverse tothe direction the implement is to be pulled across the field in normaluse and 5 feet in length. Such an implement is too wide to be pulleddown a public road in its normal direction of travel.

In the prior art it is old to mount a turntable on a trailer to have avehicle that has a length in its normal direction of travel greater thanits width driven onto a turntable extended generally at right angles tothe trailer body and then rotate the turntable relative the trailer bodyso that the length dimension of the turntable extends in the samedirection as the trailer body. Further it is old to provide a pair ofwheels that are secured to the longest dimension of the implement thatare lowered to permit the implement being transported in a directionrotated 90 from its normal travel direction (see for example U.S. Pat.No. 2,996,307 to De Bailleux).

The first mentioned type of prior art apparatus requires that theimplement be moved up a ramp and thence onto the turntable, or lifted bya separate vehicle onto a turntable, and that the turntable be at leastthe same length as the longitudinal spacing of the wheels of thevehicle. The first mentioned type of prior art apparatus would require aturntable of larger dimensions than are practical for an over the roadtrailer (and thus there is no practical advantage in using such priorart apparatus) for hauling implements having a width dimension greaterthan its fore and aft dimension in its normal direction of travel. As tothe second type of prior apparatus, this requires that the vehicletravel on a road surface which may be satisfactory for relatively shortdistances in the country, but is not satisfactory for longer distances.In order to solve problems of the above mentioned nature and otherproblems, this invention has been made.

SUMMARY OF THE INVENTION Trailer apparatus having a trailer body, aturntable mounted on the body for rotation about a vertical axis, and animplement lift and support assembly mounted on the turntable formovement therewith and movement relative thereto for lifting animplement and supporting the implement in an elevated condition, saidassembly being adapted for carrying three-point hitch BRIEF DESCRIPTIONOF THE DRAWINGS FIG. 1 is a front perspective view of the trailerapparatus of this invention with the turntable lift support assembly ina datum implement pick-up position;

FIG. 4 is an enlarged fragmentary view of the lift and support assemblyin the position of FIG. 1, part of said view being shown in verticalcross section; said view being generally taken along the line and in thedirection of the arrows 4-4 of FIG. 6;

FIG. 5 is an enlarged fragmentary view of a turntable lift and supportassembly in an implement support, road travel position; and

FIG. 6 is a fragmentary horizontaLcross sectional view generally takenalong the line and in the direction of the arrow 66 of FIG. 4 to showthe mounting and construction of the turntable.

Referring to FIG. 1, the apparatus of this invention, generallydesignated 10, includes a trailer body 11 having left and right wheels12 and 13 rotatably attached thereto and a forwardly extending drawbar14. A third wheel assembly 15 is mounted by the crank member 16 on thedrawbar whereby turning the hand crank, the elevation may be varied.

Mounted on the left rear portion of the trailer body is an arcuatesupport 19 that extends through an angle greater than but less than 270to open rearwardly. The support has a vertical flange 19b and a top,generally horizontally inwardly extending flange 19a that is spaced asubstantial distance above the floor 11a of the trailer body. Mounted bythe trailer body floor and support 19 for rotary movement about avertical axis is a turntable implement lift and support assembly,generally designated 20. The assembly 20 includes a horizontallyelongated bar 21 that is of a length less than the diameter of supportflange 19b. A suitable bearing and pivot member 22 mounts the bar 21 onthe floor to pivot about pivot member 220 that has a vertical axis thatis co-extensive with the center of curvature of flange 19b. A pair ofhorizontal tubes 24 are mounted on the horizontal channel 23 to be inaxial alignment, substantially spaced from one another, and located at ahigher elevation than flange 19a; channel 23 being mounted on bar 21 topivot therewith. The tubes rotatably mount a horizontal shaft 25 thatextends outwardly of the remote ends of the tubes 24, each end of theshaft 25 having the one ends of the elongated bars 26 fixedly attachedthereto to extend outwardly therefrom at the same angle.

A tubular member 29 is pivotally mounted on shaft 25 intermediatetubular members 24, tubular member 29 mounting the one end of thecylinder 30 of a piston cylinder combination 30,31 to extend radiallyoutwardly therefrom. The aforementioned piston cylinder combinationincludes a piston rod 31 that mounts a cross head 32 to extendperpendicular to the axis of elongation of the piston rod. It is to beunderstood that a screw jack could be used in place of said combination30,31, however, it is preferred that said combination be used.

One end of the cross head 32 mounts the pivot member 33 which in turnpivotally mounts the one ends of a pair of elongated links 34. Theopposite ends of link 34 are pivotally connected at 35 to a bracket 36which in turn is mounted on the intermediate portion of a horizontalchannel 37. The channel 37 extends between bars 26 and is welded theretoat positions more clearly adjacent the ends of the bars having slots 39than the ends that are secured to shaft 25. Bar 37 is mounted inparallel relationship to shaft 25. The end of the cross head oppositepivot member 33 mounts a pivot member 44 in parallel relationship topivot member 33. The one ends of a pair of elongated links 43 arepivotally mounted by the pivot member 44 while the opposite ends arepivotally connected at 45 to a bracket 46. The lower end of bracket 46is mounted to a radially extending frame member 47 at a location remotefrom the vertical 'pivot 22a. Links 43 are of a greater length thanlinks 34.

The one ends of horizontal brace 47 is attached to the center of bar 21to extend perpendicular thereto while the other end is attached to asemi-circular vertical flange 48. The terminal ends of flange 48 arewelded to the end portions of bar 21, the radius of curvature of flange48 being substantially less than the radius of curvature of flange 19b.Angularly intermediate brace 47 and one end portion of bar 21 is asecond radially extending brace 50 while angularly intermediate theopposite end portion of the bar 21 and brace 47 is a second brace 51.Each ofbraces 50,51 has one ends attached to bar 21 adjacent brace 47-and opposite ends to flange 48, braces 50,51 mounting upwardly extendingbrackets 52 that are located radially more closely adjacent pivot member220 than bracket 46.

Each of the brackets 52 mounts a pivot member 54 to pivot about ahorizontal axis co-extensive with the other pivot member 54. The pivotaxis of the pivotmembers 54 are parallel to the pivot axis of tubularmember 29 and pivot members 33 35, 44 and 45.

Each pivot member 54 pivotally mounts the one end of an elongated link56, the opposite ends of the links having a plurality of apertures 57for mounting the bolt 59 in selected radial spaced positions from pivots54. The bolt 59 mounts the one end of the attachment bar 60, to pivotabout an axis parallel to shaft 25, the opposite end of the attachmentbar having a plurality of spaced apertures 61.

Angularly spaced wheels 64 are mounted by flange 48 to rotate abouthorizontal axes that pass through pivot member 22a. The wheels 64 aremounted intermediate flanges 48,49 in a position to rotatably bearagainst the under surface of flange 19a to aid in retain- 1 ing theangular intermediate portion of flange 48 closely adjacent the trailerfloor. Wheels 64 are mounted such that at least one is abuttable againstflange 19a even when the turntable is rotated 90 from the implementpick-up position.

Mounted on the trailer floor forward of arcuate support 19 is ahorizontal, rectangular tubular member 66 which has an elongated slidebar 67 slidably extended therethrough. Bar 67 is provided with aplurality of horizontally spaced, vertical apertures (not shown),

while tube 66 is provided with an aperture through which pin 68 isextended, the pin being extended into one of the apertures of bar 67 forretaining bar 67 in an adjusted position relative tube 66. The end ofthe bar 67, remote from the side of the trailer floor on which theturntable assembly is mounted, has a horizontal crossbar 69 mountedthereto to rest on the trailer floor. The lower end of a vertical tube70 is mounted on the center portion of cross piece 69. Tube 70telescopically mounts a tube 71, there being provided a pin 72 foradjustably retaining tube 71 in various selected vertical elevations.

- The turntable lift and support assembly in an implement pick-upposition of FIG. 4 is located on the rear, left-hand half of the trailerwith the pivot axis of pivot member 22a being slightly ahead of the axisof rotation 85 of wheels 12,13. In the pick-up position, the slotted endportions of parallel arms 26 are located rearwardly of the trailer, theaxis of pivotal movement of shaft 25 being parallel to axis of rotation85 of wheels 12,13 at this time. Preferably the maximum width of thetraile is 8 feet.

Using the apparatus of this invention, with the piston cylindercombination in its retracted position and the turntable rotated to theimplement pick-up position, such that arms 26 extend rearwardly, thetrailer is backed up to the implement 75 to be hauled such that the axisof rotation 85. of wheels 12,13 is generally parallel to the widthdimension of the implement and the slotted ends of arms 26 are adjacentthe lower two hitch points of the implement. Pins 63 are withdrawn andarms 26 moved so that the two lower hitch points are located in slots 39and then pins 63 repositioned to retain the lower two hitch points inthe slots while permitting said hitch points pivoting in the slots. Theapertured end of bar 60 is attached to the upper third hitch point ofthe implement whereby the hitch bar 60 may pivot relative to theimplement. Now fluid under pressure is applied to the lower end ofcylinder 30 whereupon the cross head 32 is moved radially away from thepivot axis of shaft 25. Since the position of pivot member 45 is fixedrelative to the turntable, this movement of the cross head results inlinks 43 being pivoted in the direction of the arrow 77 about pivotmember 45 and the cross head and piston cylinder combination pivoted inthe direction of the arrow 78 relative the axis of shaft 25. Theaforementioned radial and pivotal movement of the cross head, throughlinks 34, pivot arms 26 in the direction of the arrow 78 about shaft 25to elevate the slotted ends of bars 26.

Initially, since the spacing of the top hitch point from the attachmentof the arms to the lower two hitch points is fixed, the aforementionedelevating movement of the slotted ends of arms 26 result in links 56being pivoted in the direction of the arrow 79 about pivot members 54.In this connection it is to be noted that the attachment of theimplement to bars 26 and bar 60 is horizontally on the opposite side ofshaft 25 from the 60 is less than I80". As a result of the relativelocations of the pivot members, the shaft pivot axis, the length of thelinks and the spacing of slots 39 from shaft 25, the rearward endportion of the implement 75 is elevated more rapidly than the forwardend portion whereby in the length direction the implement is inclined.After the implement is elevated to an elevation to avoid striking thefenders lle of the trailer when the turntable assembly is rotated, theapplication of additional fluid under pressure to the lower end of thecylinder is discontinued and while the cross head is retained in itselevated position relative the cylinder, the turntable (for example bypushing on bars 26) is rotated about the pivot axis of pivot member 22awhereby the elongated width dimension of the turntable extends generallyfore and aft with the implement in part in overhanging relationship tothe right-hand half trailer. That is, at this time, the implementextends over the right-hand portion of the trailer and depending on thelongitudinal dimension of the implement, in part extends to the right ofthe trailer. Now tube 67 is horizontally adjustably positioned relativetube 66 and the elevation of tube 71 is adjusted relative tube 70 to theproper elevation to have the upper end of the tube 71 attached to aframe member of the implement. Tubular members 71,70 support the tubularframe intermediate the mid-portion thereof and the now forward end ofthe implement. A chain (not shown) has one end attached to the forwardend of the implement (on the opposite side of tube 70 from arm 26) andthe opposite end attached to the drawbar to aid in retaining theimplement in a generally horizontal position in a fore and aft directionof the trailer and inclined upwardly in a transverse direction towardthe right of the trailer.
